Homework Statement
Let the probability density function##f(x) = (3/4) \cdot (1-x^2)## if x is between -1 and 1, and let ##f(x)=0## otherwise.
What is the probability of ##P(X \leq 0.8 | X>0.5)##?
Homework Equations
The Attempt at a Solution
I assume I have to rewrite the p.d.f. into a joint probability density function so I can use bayes' rule?
And what does the large "##X##" mean in probabilities? Often my texts uses large X-es instead of small. Is the large X for the actual event, while the small x is just a function variable?
